Answer: C
IPv6 defines an IP address of 128 bit.
IPv6 addresses are 128 bits long, usually written as eight groups of four hexadecimal digits, which allows about 3.4 × 1038 addresses. IPv6 was introduced because the 32-bit addresses of IPv4, about 4.3 billion of them, were running out.
32 bits is the size of an IPv4 address. 64 bits is the size of the interface identifier in a typical IPv6 address, half the address, and 256 bits is not used.
